Cannot establish WiFi connection

After a new reinstall of UCS 5.0 I am having troubles with WiFi connection. I get a message ‘Cannot locate servers’ and I am asked to navigate to the following address instead of I tried to go into recovery mode but still having issues with a reliable connection. Any help would be appreciated Thanks… Tommy

Do you really believe, that anybody can help you without any knowledge about your hardware an network?
Do you use more than one UCS in your network?
Why don’t you use ethernet connection - it is faster than WLAN?
Did you configure your network-settings on UCS with a static network address?

Is this your external IP-address? - If it is so, is the port forwarding (port 80 AND 443) set to the correct internal IP address of your UCS?
